SPECIFICATION forming part of Letters Patent No. 782,493, dated February 14, 1905.

A i Application filed August 17, 1901. Serial No. 72,340.

To all whom it may concern..-

Be it known that I, IsAAc O. DAY, a citizen of the UnitedStates, residing at Ottumwa, in the county of Wapello and State of`Iowa, have invented a new and useful Pump, of which the following is a specification.

rlhis invention relates generally to pumps, and has for its object to provide a simple and efficient means whereby the water can escape from the pump-barrel,and thereby avoid freezing within the barrel. c' n With this object in view the invention consists in the peculiar construction of the various parts and in their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.l

In the drawings forming part of this specification, Figure 1 is a sectionalview ofthe pump constructed in accordance with my invention. Fig. 2 is an enlarged sectional view of the check-valve mechanism. Fig. 3 is a horizontal sectional view taken through the plunger-rod above the connecting-pin. Fig. 4 is a detail perspective View of the float, and Fig. 5 isa detail perspective View showing the end of the plunger-rod.

This invention is particularly adapted for use in connection with driven wells.

Referring to the drawings, A indicates the pipe, which is driven into the earth. The

pump-barrel B is connected at its upper endA to a collar O, which is secured to the platform D, and the head of the pump E is also connected to this collar C.' The pump-barrel has a cylinder F suspended therein, the said cylinder being slotted at its lower end, as shown at F', and working through this cylinder is the reciprocating plunger-rod G, carrying the plunger or piston H at its lower end, having the usual valves H'. The lower end y of the pum p-barrel is closed by means of a casting I, said casting having a central opening K, which is surrounded by a depending collar L, threaded internally and into which the pipeAscrews. Upon the inner face of the casting and surrounding the central opening K is an` externally-threaded collar M, forming a Valve-seat upon which screws the cage vN. The casting has an upwardly-projecting internallythreaded iange I', by means of which the 4casting is connected to the lower end of the f barrel B. The valve O has a depending tubularportion O', which extends down into the circular opening K, said valve resting upon a washer O2, which rests upon` the top of the collar M. The valve O rises and falls in the cage N, and, if desired, a nut O3 may be screwed upon the depending portion of the valve. A minute opening is formed in the valve O, through which the water may slowly drain back below the valve. eled upon the end of a rod Q, which is con- -A ball-valve Pis swivnected at its upper end to a 'pin R, said pin passing through the depending lugs S, arranged uponthe under side of an annular iioat S, which works freely upon the lower end of the plunger-rod Gr, said plunger-rod being slotted longitudinally, as shown at G', to permit the pin R to pass therethrough, so that the float can rise and fall upon the plunger-rod.

-When the iioat S is in its lowermost position,

as shown in Fig. l, the slots G are entirely covered, the fioat S fitting the plunger-rod Gr snugly, so that air is not admitted to or through the slots G. The lower end of the cylinder F is slotted, as shown at F', so that when the lo'at S rises to its highest position it does not close the lower end of the cylinder, so as to prevent admission of water to the said. cylinder.

In operation the plunger-rod is reciprocated by means of the ordinary handle'or lever, and the water will pass upwardly through the pipe A, lifting the valve O and passing up through cageN. The check-valveP is of course elevated at this mornent. Upon thedescent of the plungerrod a portion of the water will be forced past the plunger H and will he elevated at the next stroke of the handle. When the operation of the pump has ceased, a porof therod @and should be suiiicient to cover the plunger or piston H, which is at all times immersed.

It will thus be seen that I provide a simple and eicient means for regulating the escape of the surplus water from the barrel of thepump.

Having thus fully describedmy invention, what I claim as new, and desire to secure by Letters Patent, isy l. The combination with a pump barrel having a valve-seat at its lower end, a valve adapted to coact with said seat,said valve bei-ng perforated, a vertically slotted plunger, a float movable on the plunger-rod and adapted to closethe slot when the float is in its lowest position, a rod carried by the float, and a ball carried by the rod last mentioned and adapted to close the perforation in the valve.'

2. In a pump, the combination with a barrel having a valve-seat at its lower end, of a valve having a seat formed thereon, a plunger-rod carrying a piston, a' fioatmovable upon the plunger-rod,and a ball suspended from the said float 'and adapted to coaet with the seat formed on the valve.

3. In a pump, the combination of a barrel having a valve-seat at its lower end and a cage protecting said valve-seat, a valve working in the cage and having a minute opening therein, of a plunger-rod carrying a piston at its lower end and working in the said barrel, an annular oat movable upon the said plunger-rod, a rod depending from the said fioat, a ballvalve carried by the lower end of said the cage and close the opening in the valve, substantially as shown and described.

4. In a pump, the combination with the barrel, of a reciprocating plunger therein, a Valve below and a float above the plunger,and means for connecting the valve with the oat in such manner that the valve will be seated before the escape of all the water above the plunger when the pump is not in use, substantially as described.

*5. In a pump, the combination with the barrel,ofa reciprocatingplunger and afloat therein below the frost-line, the float being above the plunger, a valve below the plunger and con- Ineeted with the iioat as to be seated before all the water above the plunger escapes when the pump is not in use, substantially as described.

6. In a pump, the combination with the barrel of a reciprocating plunger-rod therein, the

lower portion of which is hollow and slotted, a

plunger on the end of the rod and a float loosely mounted on the rod at the slotted portion, a pin through the slots and in engagement with the loat, a rod connected with the pin and extending below the plunger through the hollow of the plunger rod, and a valve loosely secured to the lower end of said secondmentioned rod, substantially as described.
